Police investigating the death of Alesha MacPhail have launched a fresh appeal for information after a male teenager was arrested on suspicion of murder.

Six year-old Alesha was reported missing on Monday morning while staying with her father and grandparents in Rothesay on Bute.

Her body was found later that day in woodland by a member of the public.

Shortly before 8pm on Wednesday, police confirmed a male teenager under the age of 18 had been arrested over Alesha's death.

It came after a car was seized on Wednesday afternoon as part of a forensic investigation of the house where Alesha was staying.

Despite the arrest, police say they are still appealing for witnesses or those who may have been in the area on Sunday night or Monday morning to contact police.

Senior investigating officer Stuart Houston said: "The response to our earlier public appeals has been significant.

"However, despite this evening's major development, I am still appealing for anyone who was in the Ardbeg Road area of Bute on Sunday night or in the early hours of Monday and who may have information about Alesha's death to contact us.

"Anyone who has CCTV at their home or business, or indeed any motorists with dash-cam footage which might help with our investigation are also urged to get in touch."

Floral tributes have been left on the island in the wake of Alesha's death, with her school describing the primary two pupil as "smiley" and "considerate".

Wendy Davie, the head of Chapelside Primary School in Airdrie, said: "Alesha started with us in August 2016 and had just finished primary two.

"She loved being at school and enjoyed all aspects of literacy, in particular writing. She was such a perfectionist in her handwriting and was very proud of her work.

"Alesha was very friendly and she welcomed everyone first thing in the morning at breakfast club."

Ms Davie added: "She was a very considerate child who loved being part of a group and she was popular with all the other children and was a smiley and happy young girl.

"She was part of the family of Chapelside Primary and she will be greatly missed by everyone at the school.

"Our thoughts and prayers are with the family, friends and Chapelside Primary community at this very sad time."

Alesha's mother Georgina Lochrane travelled from her home in North Lanarkshire to the island on Tuesday.

Rev Owain Jones said people had been "stunned" by the death and murder investigation.

He has opened his United Church of Bute in Rothesay to allow people to visit at any time.

He said: "We're all absolutely staggered, we have no words for this and it's beyond any power of words to express.

"We're all just really sitting in a kind of shared stunned silence just trying to uphold each other.

"Bute is one of these places that is incredibly safe, you take all sorts of things for granted here and don't panic if you forget to lock the house or whatever."
